A sandwich panel is any structure made of three layers: a low-density core (PIR, mineral wool, XPS), and a thin skin-layer bonded to each side. Sandwich panels are used in applications where a combination of high structural rigidity and low weight is required. The structural functionality of a sandwich panel is similar to the classic I-beam, where two face sheets primarily resist the in-plane and lateral bending loads (similar to flanges of an I- beam), while the core material mainly resists the shear loads (similar to the web of an I-beam). The idea is to use a light/soft but thick layer for the core and strong but thin layers for face sheets. This results in increasing the overall thickness of the panel, which often improves the structural attributes, like bending stiffness, and maintain or even reduce the weight.

Eps sandwich panel is a kind of lightweight energy saving wall material, which uses cement calcium silicate or reinforced calcium silicate board as face panel, filled with cement, expanded polystyrene (EPS) foam particles, and as core material and forming by one time compound. Eps sandwich panels are made by mixing Eps polystyrene foam particles, cement, sand, calcium silicate board, additives and other raw materials at a proper ratio. Eps sandwhich panels production line mainly including four parts: mixer system, foaming system, mould system and transition system.

Rockwool sandwich panel on both sides gives full play to the unique properties of rock wool core material, the fire prevention, heat preservation and heat insulation, sound-absorbing, sound insulation, etc. First of all, the sandwich panel features excellent fireproof performance. With the raw material, production technology and formula of the rock wool sandwich wall panel, it has good fireproof performance. Sound insulation and sound absorption effect is remarkable. Rock wool sandwich panel has a significant reduction effect on noise transmission, especially for designated flights. What's more, it has remarkable effect in fire prevention, heat preservation and heat insulation. It can be widely used in the steel structure factory building, activities room, roof, wall, air clean room ceiling and partition.

Pu sandwich panel is composed of 3 layers, the external and internal is two dyed galvanized or aluminum corrugated plates, and core high density polyuretahe foam. Thanks to their properties the panels may be applied in object that require very high fire resistance, PU sandwich panel is the most effective acoustic materials used on construction. PU sandwich panel has ranked high in terms of R-value. The thickness of PU sandwich panel comes in various measures which are 40, 50, 75, 100, 200mm and its density is one of the best you can get from an insulation panel with a value that ranges from 38-45kg/m3.

C/Z purlin (or historically purline, purloyne, purling, perling) is a longitudinal, horizontal, structural member in a roof. In traditional timber framing there are three basic types of purlin: purlin plate, principal purlin, and common purlin. C/Z purlins also appear in steel frame construction. Steel purlins may be painted or greased for protection from the environment. In steel construction, the term purlin typically refers to roof framing members that span parallel to the building eave, and support the roof decking or sheeting. The purlins are in turn supported by rafters or walls.

Once properly installed, a metal roofing sheet is capable of lasting as long as the house is standing for the reason that metal roofing sheet doesn’t rot or crack, neither does it warp or curl. The shingles or panels doesn’t break or split, nor can they burn and the design doesn’t peel off for ages. Metal roofing sheet seals off water, capable of surviving high winds and it can shed snow and thawing quickly. Metal also can resist fire, insects, mildew and wane.

In architecture, a deck flooring is a flat surface capable of supporting weight, similar to a floor, but typically constructed outdoors, often elevated from the ground, and usually connected to a building. The deck of a house is generally a wooden platform built above the ground and connected to the main building. It is generally enclosed by a railing for safety. Access may be from the house through doors and from the ground via a stairway. Residential decks can be constructed over steep areas or rough ground that is otherwise unusable. Decks can also be covered by a canopy or pergola to control sunlight.
